The equation for distance is d, t how far does a car go in 10 seconds at a speed of 44 m/s?

First of all, ' d,t ' is not an equation.  

The equation for distance is: Distance = (speed) x (time)

Distance = (44 m/s) x (10 sec)

Distance = 440 meters

b) 10 minutes

girls stopped for 10 minutes.

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
